Britney Spears has dinner with Mel Gibson

It's time for more fantastic Celebrity Dinner Watch!

This go around, it seems one Britney Spears showed up at Romanov Russian Restaurant & Lounge in Studio City to meet with our favorite DUI directing nut job, Mel Gibson, Us says. (See video above of Brit walking in and then -- amazingly! -- back out again later the same day!)

We can only guess why Mel and Brit Brit met up, but Us does point out that Mel's wife Robyn was hatin' all over Bratney last year when the two then-neighbors in Malibu were fretting over wildfires. The New York Observer quoted Robyn as saying "It's so annoying that people are more concerned about if Britney Spears' house was burnt than their own well-being."

While the two may have been discussing public feauds, real estate or even jail time, The Juice* prefers to think Mel is casting her in a new movie about a drug addled pop star who marries a lowlife and ruins her career. It's called Whitney.
